Prnp Gene Summary [Rat]
Enables several functions, including ATP-dependent protein binding activity; lamin binding activity; and transmembrane transporter binding activity. Involved in several processes, including negative regulation of long-term synaptic potentiation; positive regulation of protein localization to plasma membrane; and response to copper ion. Located in postsynaptic density. Used to study hyperglycemia and scrapie. Human ortholog(s) of this gene implicated in Creutzfeldt-Jakob disease; Gerstmann-Straussler-Scheinker syndrome; Huntington's disease-like 1; fatal familial insomnia; and kuru. Orthologous to human PRNP (prion protein (Kanno blood group)). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Prnp often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
